The dusty mocassin: fully self-consistent 3D photoionization and dust radiative transfer models.
ERCOLANO B., BARLOW M.J. and STOREY P.J.
Abstract (from CDS):
A set of rigorous benchmark tests have been carried out for dust-only spherically symmetric geometries and 2D disc configurations. The results of mocassin are found to be in agreement with those obtained by well-established dust-only RT codes that employ various approaches to the solution of the RT problem.
A model of the dust and of the photoionized gas components of the planetary nebula NGC 3918 is also presented as a means of testing the correct functioning of the RT procedures in a case where both gas and dust opacities are present. The two components are coupled via the heating of dust grains by the absorption of both UV continuum photons and resonance line photons emitted by the gas. The mocassin results show agreement with those of a 1D dust and gas model of this nebula published previously, showing the reliability of the new code, which can be applied to a variety of astrophysical environments.
